Many thanks for that tipp ChezJfrey, it actually worked.
But it downloaded the mod without an .exe file. Any help?
There is no .exe in any of the mods, including ERAS. The .exe and .dll modules are all within the Maelstrom download and you can create multiple shortcuts, pointing them do the single .exe, but all the different mods. That way if Maelstrom gets updated, there is just a single point to update for the engine.
